Nanoclay nucleation effect in the thermal stabilization of a polymer nanocomposite: A kinetic mechanism change
(American Chemical Society, 2012)
The enhanced thermal stability of polymer-clay nanocomposites over the original polymers is one of their most interesting features, and it has been profusely studied within the last decades. Here, a thorough kinetic analysis ...

Characterization of mechanosynthesized Bi1−xSmxFeO3 samples unencumbered by secondary phases or compositional inhomogeneity
(Elsevier, 2017)
High-quality samples, in terms of phase purity and dielectric properties, of composition Bi1−xSmxFeO3 (0.05 ≤ x ≤ 0.20) have for the first time been prepared by mechanosynthesis. Close inspection of the powder diffraction ...

Relevant influence of limestone crystallinity on CO2 capture in the Ca-looping technology at realistic calcination conditions
(American Chemical Society, 2014)
We analyze the role of limestone crystallinity on its CO2 capture performance when subjected to carbonation/calcination cycles at conditions mimicking the Ca-looping (CaL) technology for postcombustion CO 2 capture. The ...
